I am a number. I am between 100 and 200. I am a square number. My digits add up to 16. I am odd. What number am I?

Answer and explanation

Correct answer: A. 169

  1. Step 1: Use the first clues to list the numbers that fit. Step 2. Test each remaining clue against that list. Step 3. Only 169 satisfies every clue. Answer: 169. Why not the others: 196: This breaks the clue 'I am odd.'. 121: This breaks the clue 'My digits add up to 16.'. 187: This breaks the clue 'I am a square number.'.
